Title: Improvements in or relating to multiple filament electric lamps
IPC: H01K9/04
Filed: 1935-04-04
Abstract: 454,852. Electric couplings. EDWARDS, L. C., 63B, King's Road, Chelsea, London. April 4, 1935, No. 10451. [Class 38 (i)] In a multiple filament electric lamp of the kind in which the lamp is supported by a ring which engages in a bayonet socket so that various contacts on the lamp may be selectively contacted with the plunger terminals of the socket by turning the lamp relatively to the ring and socket, the ring is continuous and. imperforate and mounted freely rotatably on the outside of the lamp cap, one or more stops or projections upon the inner surface of the ring co-operating with one or more arcuate grooves, notches, or depressions in the lamp cap whereby the ring is kept in place laterally on the cap and relative turning movement of the ring and cap is limited. In one form, the ring 12 Fig. 4, is kept in place laterally on the cap 9 by the engagement of the heads 14 of the bayonet pins 13 in arcuate grooves 15 formed in the cap. A shoulder 10 is also provided on the cap to check downward lateral displacement of the ring 12. Admission of the heads 14 to the grooves 15 is provided by entry grooves at the upper edge of the cap, these entry grooves subsequently being rendered ineffective, as by punching. In an alternative construction, the cap is provided with one or more pins or projections 25, Fig. 6, which co-operate with grooves or cutaway portions 24 on the edge of the ring. In a further modification, the cutaway portion 24 is formed at either end with recesses into which the co-operating projection on the lamp cap can spring. Alternatively, a cutaway portion or portions may be formed in the lower edge of the ring, to co-operate with a stop or projection on the cap, lateral displacement of the ring being prevented by the heads of the bayonet pins engaging a groove or grooves in the cap. Specification 376,939, [Group XI], is referred to.

Title: Thiosemicarbazones
Filed: 1951-05-04
Abstract: The invention comprises the mono- and di-thiosemicarbazones of phthalaldehydes and their preparation by reacting a phthalaldehyde with thiosemicarbazide.  The monothiosemicarbazones may be further reacted with amino compounds such as aminosalicylic acid or 4-aminobenzal-thiosemicarbazide.  In examples: (1) terephthalaldehyde is reacted with thiosemicarbazide in hot water to give the di-thiosemicarbazone; (2) terephthalaldehyde is reacted with thiosemicarbazide in aqueous alcohol to give the mono-thiosemicarbazone; (3) isophthalaldehyde is reacted with thiosemicarbazide in acidic aqueous alcohol to give the mono- or di-thiosemicarbazone, and the mono- and dithiosemicarbazones of orthophthalaldehydes are similarly produced; and (4) terephthalaldehyde is reacted with thiosemicarbazide in the presence of water, methanol and hydrochloric acid to yield the monothiosemicarbazone.

IPC: G10F5/02
Abstract: 105,803. Fairweather, H. G. C., (Green, W. R.). May 3, 1916. Piano-players and playerpianos; actions, electromagnetic. A series of electro-magnets is arranged in proximity to a rotary shaft of magnetic material, which serves as a common armature; on excitation, the magnets cling to the shaft and are moved thereby to strike the notes. Movable magnet coils may be connected by flexible or jointed connexions, hut preferably the coils are fixed and the cores movable. As shown in Figs. 3 ancl 4, the oblong coils 21 are mounted vertically within laminated cores 13 of U-shape; the two upper and one of the lower laminations are cut away as shown at 24 to reduce friction before and after the stroke, and the lowest is non-magnetic. The shaft 14 of soft iron or steel is preferably made hollow with a seam of non-magnetic material to assist in releasing the magnets. The cores may be connected directly to the hammer action. In the pianoplayer shown in section in Fig. 1, the cores 13 are adjustably connected to levers 16, 16<a> with plungers of different lengths for the black and white keys. The coils 21 are connected individually to the contacts of! a tracker T and collectively to a bar 42, rheostat 64, and brush 35. The shaft 14 is driven through gearing and a universal joint from a handle on an angularly disposed crank-shaft, which drives also the tune-sheet. Cases for piano-players. The cover 12 and base 10 are made in removable sections connected by end and intermediate plates; the base is shaped to conform to the keys of the instrument.

Abstract: 809,949. Aircraft undercarriages. BRITISH MESSIER Ltd. April 3, 1957 [April 6, 1956], No. 10636/56. Class 4. An aircraft bogie undercarriage comprises a main leg 11 pivoted at its upper end to the aircraft, a trailing link 13 pivoted at its forward end to the lower end of the leg, a bogie frame 14 pivoted between its ends at 16 to the rear end of the trailing link and carrying land wheels 17, 18 (preferably in transverse pairs) fore and aft of its pivot, and a telescopic shock absorber 19 adjacent the leg and pivoted at its upper end to the leg and at its lower end to the bogie frame or to the link rearwardly of the pivot between the link and the leg, whereby raising and lowering of the bogie on the link with respect to the leg causes contraction and extension of the shock absorber. The leg is transversely pivoted at 24 to a member 25 pivoted to an aircraft wing on a fore-and-aft retraction spindle 27. Retraction is effected by a jack (not shown) acting to rotate member 25. A telescopic side-stay is connected between the wing and the leg. A drag strut 30 is connected between the wing and the leg as described in Specification 809,950. A telescopic bogie damper 21 is connected between the leg and the nose of the bogie, so that the bogie is in a nose-up attitude on touch down. Brake compensating links are provided, a pair 37 (one shown) connected between non rotary parts of the front wheel brakes and one arm of a bell crank lever 34, and a single link 38 connected between non rotary parts of the rear wheel brakes and the other arm of the bell crank lever. A link 39 extends between the other arm of the bell crank lever and a pivot on the leg 11, so as to be parallel to the trailing link. Each link 37, 38 is disposed so that it axis and the line joining the pivot of the leg and bogie frame to the corresponding wheel axis, intersect at ground level as shown. Fig. 1 shows the shock absorber 19 pivoted on the pivot 16 between the leg and the trailing link, but to compensate for the moment about pivot 16 caused by the rolling resistance of the wheels, the shock absorber may be connected to the bogie frame rearwardly of pivot 16.
